Re: How to get the reflectivity from water by modis on seadas

ncdump -h level-2file > file_to_attach.txt Thank you very much, Unfortunately, I didn't understand how to share data. Does this code :"ncdump -h level-2file > file_to_attach.txt" run in the terminal? I downloaded daytime and after seadas atmospheric correction l2gen, the result is still NaN.

Re: How to get the reflectivity from water by modis on seadas

This is the processed data: A2015017174500.L1B_LAC (Sorry, I cannot add it to the attachment due to the file size limitation), and the value obtained during atmospheric correction Rrs and Lw etc is NaN .

How to get the reflectivity from water by modis on seadas

Hello everyone,
When I was using seadas7.5.3--OCSSW--l2gen to process modis data in order to obtain the reflectivity of the water body, I only got the reflectivity of the land and the reflectivity of the water body was negative. What parameters should I set to get the desired result?

Thanks,
ding
